Active Measurement Admission Control for Network Resource Optimization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Active measurements in communication networks often disrupt idle or sleep modes, leading to increased battery drain and signaling overhead, as they require maintaining radio bearers even when not necessary for active communication, thus affecting network efficiency and user equipment power consumption.
Innovation Solution
Implementing an active measurement admission control system that determines the availability of critical resources and only initiates measurements when these resources are active due to other activities, using a method that involves obtaining maximum permitted subsession durations and time margins, such as sleep-init times, to minimize the impact on idle periods and optimize resource usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If active measurements are performed continuously to ensure accurate performance monitoring, then measurement precision is improved, but battery consumption increases and idle/sleep modes are disrupted
Solution Approach 1:
The patent implements periodic action by scheduling active measurements only during specific time windows when radio bearers are active, rather than continuously. The system determines whether critical resources are active due to other activities before initiating measurements, and uses time margins (sleep-init time) to identify appropriate measurement opportunities, thereby reducing battery consumption while maintaining monitoring capability
Solution Approach 2:
The patent applies dynamics by making the measurement schedule adaptive rather than static. The system dynamically adjusts measurement timing based on the actual activity state of critical resources (radio bearers), using obtained time margins to flexibly determine when measurements can be performed without disrupting idle/sleep modes, thus optimizing the balance between measurement accuracy and energy consumption
2Productivity
If active measurements are performed frequently to maintain up-to-date performance data, then productivity is improved, but signaling overhead increases
Solution Approach 1:
The patent reduces signaling overhead by implementing periodic measurements only during active periods of critical resources. Instead of frequent continuous measurements, the system schedules measurements periodically when radio bearers are naturally active, thereby maintaining performance data freshness without generating excessive signaling traffic during idle periods
Solution Approach 2:
The patent applies self-service by utilizing existing radio bearer activity for measurements rather than creating separate dedicated measurement bearers. The system determines whether critical resources are active due to other activities and leverages this existing activity to perform measurements, thereby avoiding additional signaling overhead that would result from establishing separate measurement resources
3Reliability
If radio bearers are maintained active for measurement purposes, then measurement reliability is improved, but loss of energy increases due to unnecessary resource activation
Solution Approach 1:
The patent applies self-service by using existing radio bearer activity that is already active for other purposes to perform measurements. The system determines whether critical resources are active due to other activities before initiating measurements, thereby leveraging existing resource activation rather than creating separate dedicated measurement bearers, which eliminates the energy waste of maintaining radio bearers solely for measurement purposes
Solution Approach 2:
The patent implements multi-functionality by using radio bearers that are activated for other communication purposes to also serve measurement functions. Instead of creating dedicated single-purpose measurement bearers, the system utilizes the universality of existing active bearers to perform both data transmission and performance monitoring, thereby avoiding the energy loss associated with maintaining separate measurement-specific resources

AI summary
A method for managing active measurements for determining performance parameters in a communication network comprises obtaining of a maximum permitted subsession duration and obtaining of time margins. The method further comprises determining whether or not a critical resource involved in the active measurement is active due to other activities than active measurements. If the determination concluded that the critical resource is active, a sending of an ensemble of packets of a subsession of an active measurement session is initiated. If there is an intended next subsession of the active measurement session and if a time since a last ensemble of packets was sent exceeds a sleep-init time comprised in the time margins, at least the determining and, if permitted, the initiating a sending of an ensemble of packets of the next subsession of the active measurement session is repeated.
